Notes:
1. Data changes at the clock rising edge so it can be safely read at the falling edge, although it can be read at the rising edge if preferred.
2. When VDD1 is not supplied, MDAT is high ie modulator output level is “1”

Notes:
1. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 6000 Vrms for 1 second. This test is performed
before the 100% production test for partial discharge (method b) shown in IEC/EN/DIN EN 60747-5-5 Insulation Characteristic Table.
2. This is a two-terminal measurement: pins 1-8 are shorted together and pins 9-16 are shorted together.
3. Maximum power dissipation in analog side and digital side IC’s needs to be limited to ensure that their respective junction temperature is less than
125°C. The maximum permissible power dissipation is dependent on the thermal impedance and the ambient temperature.

De nitions
Integral Nonlinearity (INL)
INL is the maximum deviation of a transfer curve from a
straight line passing through the endpoints of the ADC
transfer function, with o set and gain errors adjusted out.
Di erential Nonlinearity (DNL)
DNL is the deviation of an actual code width from the
ideal value of 1 LSB between any two adjacent codes in
the ADC transfer curve. DNL is a critical speci cation in
closed-loop applications. A DNL error of less than ±1 LSB
guarantees no missing codes and a monotonic transfer
function.
O set Error
O set error is the deviation of the actual input voltage
corresponding to the mid-scale code (32,768 for a 16-bit
system with an unsigned decimation  lter) from 0 V. O set
error can be corrected by software or hardware.
Gain Error
Gain error is the the di erence between the ideal gain
slope and the actual gain slope, with o set error adjusted
out. Gain error includes reference error. Gain error can be
corrected by software or hardware.
Signal-to-Noise Ratio (SNR)
The SNR is the measured ratio of AC signal power to noise
power below half of the sampling frequency. The noise
power excludes harmonic signals and DC.
Signal-to-(Noise + Distortion) Ratio (SNDR)
The SNDR is the measured ratio of AC signal power to
noise plus distortion power at the output of the ADC. The
signal power is the rms amplitude of the fundamental
input signal. Noise plus distortion power is the rms sum
of all non-fundamental signals up to half the sampling
frequency (excluding DC).
E ective Number of Bits (ENOB)
The ENOB determines the e ective resolution of an ADC,
expressed in bits, de ned by ENOB = (SNDR − 1.76)/6.02
Isolation Transient Immunity (CMR)
The isolation transient immunity (also known as Common-
Mode Rejection or CMR) speci es the minimum rate-of-
rise/fall of a common-mode signal applied across the
isolation boundary beyond which the modulator clock or
data is corrupted.
